Kleineweiers Sohne Maschinenfabrik, Krefelei', Ger- The present invention relates to a device for use in connection with bleaching, dyeing, steaming and thermotreatment of web material, especially Wide textile materials in which the goods which may have been impregnated and are wound on drums or cores or are wound up during the treatment process are subjected to a treatment in air-tight retaining or processing chambers. Such semi-continuous treatment processes are customary, particularly in connection with the bleaching and dyeing of textiles.

With these methods it is increasingly customary, in addition to arranging one or more drums or cores alone in the treatment chambers, to move such drums or cores into the treatment chamber together with the drum carriage. The stationary chambers employed in this connec tion have the advantage that when employing a number of drum carriages, only a few chambers are required. However, the drawback of these stationary chambers consists in that all parts of the drum or core carriage including the carriage frame are subjected to chemical corrosion in view of the chemicals used in the treatment process, which fact leads to an early wear of the core carriage. In an effort to overcome this drawback, it has been suggested to provide each core carriage with a closed treatment chamber. The drawback of this method is seen in the fact that in addition to involving high costs, the required additional devices for heating and guiding the goods together with the respective connections have to be built into each core carriage. Moreover, the servicing and above all the introduction of the goods and the winding of the goods on the core is, in view of the closed chamber, somewhat difficult and difiicult to control.

It is, therefore, an object of the present invention to provide an arrangement for treating web material, especially textiles, in treatment or retaining chambers, which will overcome the above-mentioned drawbacks.

It is another object of this invention to provide an arrangement asset forth in the preceding paragraph which will permit the easy introduction of the core of the corecarriage into the treatment chamber and the winding and treatment of Web material on the core, While not affecting the core-carriage.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

FIGURE 1 diagrammatically through an arrangement according tion, said section being taken along URE 2;

FIGURE 2 represents a section taken along line 11-11 of FIGURE 1;

FIGURE 3 illustrates in side view a modified arrangement according to the present invention which differs from that of FIGS. 1 and 2 primarily in that the treatment chamber has two pivotally arranged sections instead of one for the insertion and the withdrawal of the core into and from the treatment chamber;

FIGURE 4 is a section through still another modification of the present invention according to which there is provided a separate pretreating chamber for airtight and illustrates a section to the present inventhe line II of FIG- 3,357,212 Patented Dec. 12, 1967 pressure-tight connection with the main treating chamber.

The present invention is characterized primarily in that the treatment chamber for the treatment of web material wound upon a core is composed of two or more sections which in closed condition encase in a pressure and air-tight manner the core only with parts of the shaft therefor, while the carriage and other installations on the carriage are located outside said treatment chamber. Said treatment chamber is so arranged that when the chamber is opened, the sections move away from each other to such an extent that the withdrawal of the treated goods and the introduction of the untreated goods or the empty core, will not be impeded. In this way, the individual advantages of the heretofore known devices are maintained without the drawbacks thereof.

According to a further development of the invention, a part of the treatment chamber is connected as a stationary part on the floor of the shop and another part of the chamber is pivotally connected to said stationary part.

More specifically referring to the drawing, FIGS. 1 and 2 show a two-sectional treatment chamber in which the separating line 5 of the two chamber sections 3 and 4 passes through the axis of the cylinder or core upon which the hank of the goods is formed. The left-hand part 3 which forms the larger part of the treatment chamber is designed as a stationary section which, by means of a base 7 is screwed to the floor of the shop. Chamber section 3 has its upper portion provided with a joint 8 to which the other chamber section 4 is pivotally connected for selective tilting in the direction of the arrow A for opening the chamber. The opening or pivoting mechanism for chamber section 4 may consist, for instance, of a hydraulic cylinder piston system 9 having one element linked to an ear 9a fastened to chamber section 3, while the other end of said cylinder piston system 9 is linked to an ear 912 connected to chamber section 4. Chamber section 4 can in this way be pivoted in the direction of the arrow A to such an extent that the core carriage 10 can, from the right-hand side (with regard to FIG. 1) introduce the core or cylinder into the treatment chamber or Withdraw the same therefrom.

In the embodiment shown in FIGS. 1 and 2, the rollers IZ-of carriage 10 have their circumferential direction parallel to the axis of the core or cylinder. The carriage 10 is moved toward the chamber 3, 4 by means of a forklift truck and is then lowered into positioning grooves 13 arranged in the floor of the shop for precisely locating the carriage in a certain position with regard to the treatment chamber 3, 4.

The web material or hank is Wound on a core or cylinder 14 which at both ends is by means of shaft studs 15 rotatably journalled in bearings 16 of carriage Iii. According to the specific embodiment shown in FIGS. 1 and 2, the core or cylinder 14 forms a perforated drum into which a treatment fluid or steam is introduced along the axis thereof through the intervention of a tubular coupling 17. Drum 14 is adapted to be rotated by a variable speed motor 19 through the intervention of a drive 18, for instance, a belt. In order firmly to hold carriage 10' while drum 14- is rotated, strong anchoring devices 30 are arranged in the foundation of the shop, as indicated in FIG. 1 by dot-dash lines.

The parting line 5 between the two chamber sections 3 and 4 is sealed by gaskets 5a or the like. The sealing by means of sealing strips of those portions which are adjacent the axle or axle studs of the drum is not expedient in view of slight deviations in the height and the lateral location of the carriage. Therefore, according to the present invention, the parting line 5 is, within the range of the drum or cylinder shaft or shaft studs, semi-circularly formed so that these areas together in closed condition of the treatment chamber confine an opening which is somewhat greater than the axle or axle studs of the cylinder, so that these semi-circular portions will not contact the axle or axle studs but will confine therewith a free space around the axle or axle studs. The thus formed. annular opening is, in conformity with the present invention, in a pressure and gas tight manner closed by flange means 20 which are .displaceable on the drum axle or axle studs. These flange means 28 are provided with elastic, preferably pneumatic annular sealing chambers 20a which in operative position of the arrangement are by spring means 21, for instance pressure springs, continuously urged and pressed against the semi-circular portions 6. The said flange means .20 are adapted to be pulled outwardly by lever means 20b so that when the chamber is opened, the drum or cylinder with the treated web material thereon can be withdrawn from the treatment chamher.

The goods to be treated are introduced into the treatment chamber 3, 4 through a properly sealed slot 22 and are then passed over driving rollers 23 and pressure rollers 24 to the winding core or cylinder 14. The drive of cylinder 14 may, of course, also be effected by the driving elements 18, 19 through the intervention of a socalled electro-winder.

In the illustrated embodiment of FIGS. 1 and 2, the driving rollers and pressure rollers are arranged within the treatment chamber, which also houses spray pipes 25 for impregnating or otherwise treating the incoming web material. After the material has been wound on the core or cylinder 14, inlet slot 22 is closed in an air-tight manner in any convenient way, and the web material on core 14 is subjected to the desired treatment while said core is being rotated.

The arrangement of FIG. 3 differs from that of FIG. 1 primarily in that the treatment chamber is composed of two sections 4a and 4b which are both pivotally supported by joints 8 carried by door'shaped frame members 26.

FIG. 4 shows still another embodiment of the present invention in which the pressure chamber is likewise composed of two pivotable sections 40 and 4d, said sections being pivotally interconnected in a pressure and gas-tight manner by a joint 27 which merges with a pretreatment chamber 28 advantageously forming a portion of the supporting frame 29. With this arrangement, the goodsreceiving cylinder or core may be supported in the same manner as described, for instance, in FIGS. 1 and 2. This also applies to the support of the goods-receiving core or cylinder of the embodiment of FIG. 3.

In all of the embodiments above referred to, those parts within the treatment chamber which are subjected to aggression by the chemicals employed in the treatment process are preferably made of non-corrosive steel or titanium or titanium alloys, or if made of corrosive material, may be covered by a synthetic material adapted to resist temperature and chemical influences. Such synthetic material is, for instance a fluorized polytetraethylene, known under the registered mark Teflon.

It is, of course, also possible to make those parts which are subjected to the influence of the treatment chemicals and temperatures of synthetic material or reinforced synthetic material, e.g. glass reinforced synthetic material. Furthermore, it is advantageous to cover the outside of the treatment chamber with any standard heat insulating material.

It is, of course, to be understood, that the present invention is, by no means, limited to the particular arrangement shown in the drawings, but also comprises any modifications within the scope of the appended claims.

What I claim is:

1. In combination with a carriage for supporting web material, axle means supported by said carriage, rotatable core means supported by said axle means and adapted to receive and support Web material, chamber means surrounding said core means and comprising side walls having susbtantially axially aligned openings therein, said axle means extending through said openings, said carriage being arranged outside said chamber means, sealing means axially displaceably mounted on said axle means, and means yieldably pressing said sealing means against said side walls for sealing said openings, said chamber means including a plurality of interconnected section means selectively movable relative to each other for opening and closing said chamber means.

2. An arrangement according to claim 1, in which said sealing means are arranged outside said chamber means.
